To all 'whom it may concern Be it known that l, HENRY Fouiner-il, a

citizen of the United StatesVresiding et;

Hazleton, in the county of ll'fucerne and State. of Pennsylvania, haveinvented cer` tain new and useful improvements in'oinbined vReinforcesand Mold-Supports for i 'Concrete Structures; end I dodeclare the saryto brace the forms and in Which a- A ollowing'to be e full, clear, andexact description of the invention, suches 'Will enable ,others skilledin theart to which it 'ap-- pertains to make end use' the seine.'

llhis inventionrelates to e combined` rey ininimum quantity of lumber isrequired to construct it. v

This invention also comprehends details l o'f construction which,together with the features above specified, will'bebetter understood byreference to the accompanying drawings, in which l Figure l represents atransverse 'vertical section of a cement Wall embodying this inventionand in which some of the mold boards have been removed showing the completed wall and others remaining in position during the setting:T ot thecement; Fig. 2`is a front elevation of a wall embodying" thisimprovement and showing some of the mold boards removed and others inoperative position. Fig. 3 is a detail perspective view of a moldsupport constructed in accordance with this invention; Fig. l is ahorizontal section showing a modified forni'of the invention; Fig. 5 isa detail perspective view of the combined anchor'and mold supportemployed -in the construction shown in Fir. 4. Fir.' 6 is a. detailperspective view of a slightly different torni of mold support providedwith means for supporting a mold to i'orm an oliiset around the surfaceof the wall to be constructed.

In the embodiment of the shown in Figs. l and 2 o. plurality ot anchorsl are employed for holding the molds or forms in operative positionduring the construction of the wall. Esch of these invention supports oranchors consists of a bar pref erably com osed' of soft steel, such asis ,known as ban`d iron and which is preterablyebout oneiiich wide byVonelsixteenth oi an inch thick, more or les wail to beconstructed andthe molds to be f used. Each of thesedevices comprises a body portion 2with prongs at its opposite l the length of, said bar conforming to thethickness of the ends to engage the upper edges o the lowermoldboardsand the lower edges ot the upperfmold boards next above as isshown clearly in'Fig." The ends ot the bar ere sheared and each bent toform teur prongs 3', 4f, 5 end, the prongs 5 and G being spaced 'a'suitable distance from the ends to span the edges of the mold boards towhich the anchor is to be applied.

The prongs 3 and 4: at the terminal of each bar are preferably termed byshearing" the bar in the center and bending` one-liali thereof laterallyin one direction and the other half in the opposite direction inposition to engage and hold the upper edge" of one board and the loweredge of the adacent board against outward movement.

f The prongs 5 and 6 are formed by striking out tongues from oppositeedges of the bar and bending one in one direction and the other in theopposite direction thereby :forming the prongs which hold the moldboardsrom inward movement. The cut ting ot these tongues which form 'theprongs 5 and G i'ormsI a weakened shank or neck 7 `for a purpose to behereinafter described. Prongs 8' are also formed by striking; outtongues from opposite edges or' the bar at points spaced inward from thenoch 7 and bending them inwardly to form pockets tor a. reinforcing baror rod 9 when such is employed as is shown clearly in Fig. 1. A l

In the use of this improved anchor and mold support a'layer of concreteor cement is first disposed in aconcavity such as a ditch upon which'thewall is to be erected. This layer is placed without forms and isaccurately leveled, and the wall is erected thereon in the followingmanner: rlChe nnchors l are placed on this foundation `sufh *cientlyclose, about two feet apart more or less, to, engage the lower edge ofthe mold I which may be of metal, wooden boards boards lined with metalof any desired design. .Then o s'uiicient number o' anchors this is donethese mold boards may be held perfectly plumV by forcing blocks orlboards 11 at intervals between the mold boards to force said boardstightly against the prongs 3 land 4C. The molds so formed may bearranged in perfect alinement and is ready to receive the concrete orcement. The blocks or boards 11 between the mold boards 10 are removedas soon as the molds have been lilled in lwith the concrete which willhold the mold boards in position without the use of any additionalboards or blocks. When this first course Iof the wall has been completedthe second boards of the mold are laced in position and the prongs and 5at the ends of the anchor will engage the opposite faces of the loweredges thereof. and hold these boards in alinement with the boards, belowwith which the prongs fiand 6 are engaged. Similar' anchors are thenengaged with the upper edges of the unfilled boards of the mold with theprongs l and 6 thereof engaging the opposite faces of said upper edgeand blocks 11 may be arranged between said-boards to force them againstthe outer prongs of the anchors if it is found to be necessary and saidboards are thereby held irmand ready to receive the second course ofcement. After these boards have been filled the blocks 11 are removed asabove described and other boards may be added in the same manner untilthe wall is of the desired height. When the lower courses have becomesufficiently hard the mold boards may be removed therefrom and usedagain on the upper courses. To remove these mold boards the outer prongsl are bent outwardly," which may be done with any suitable tool, above`the upper edges of the lower mold boards with which they are engagedand these boards 10 may then be easily withdrawn for use on succeedingcourses, the withdrawal thereof also bending theprongs 3 of the anchorbelow, which engages the lower edge thereof, downwardly as is shownclearly in Fig. 1. .After removing the mold boards 10 the outer portionsof the anchors are' twisted thereby breaking them off at the necks 7which are disposed within the concrete wall not less than one-half inchfrom the outer face thereof. By forming these weakened necks the oulerends of the anchors may be readily bro ren by twisting them back andforth oncev twice and when the protruding board supporting ends havebeen removed the recesses left in the outer face ofthe wall are pointedup or cemented over producing a perfectly smooth outer face andcompletely covering the anchor and thus prevering rust stains on thesurface of the wa During the construction of the wall before the cementis filled into the molds if it is desired to strengthen the wallslongituprong 12 is bent downwardly it will engage Y the outer face ofthe` upper edge of the mold board and corresponding anchor disposed atthe lower edge of said mold board has the tongue 12 extended upwardly tohold the board 10 in position to form the oii'set as is shown clearly inFig. l.

In the form shown in Figs. 4 and 5 a wall is shown constructed withconcavities or spaces between one face thereof and the plastering 13.The boards 14 employed in forming the inner face of the wall shown in.these figures are arranged vertically the entire height from door toceiling thereby forming a vertical joint between the mold board on theinside of the wall and horizontal joints in the mold boards forming theouter surface of the wall. (See 14 and 15 of Fig. 4).' These mold boards11i are preferably provided with wooden studs or bars 16 having nails 17driven therein from the inside and cast in the concrete when poured tohold said studsA in place and to which the lathing is attached on whichthe plaster walls 13 are mounted. The form of anchor employed inconnection with this style of wall is shown in Fig. 5 in which one endthereof is constructed similarly to the anchor described and shown inFigs. 1 and 2, the other end of said anchor is twisted to dispose theprongs 3', 4c', 5 and 6 laterally instead of vertically as in the otherfigures to adapt these prongs for engaging the vertical mold board 14.The twisting, however, is not confined to the neck but it may be done atany point de sired.
